SUSPENSION DEVICE.

Specification of Letters Patent.

Patented Jan. 3, 1922.

T0 all whom t may cof/wem:

Be it known thatI, WILLIAM; C. STARKEY, a citizen of the United States of America, residincr at Mansfield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements-in Suspension Devices, of which the following is a specification. l v

My invention relates to a device for engaging and supporting a conductor and more particularly to that class of conductors known as trolley wires or trolley conductors.

My invention has for its object a device which can be made to quickly grip or engage the trolley wire through the medium of a cam action and in the particular form of device shown and described the grip comprises a duplex engagement in that there are two cams, one for directly engaging the conductor and the other for forcing a member into engagement with the conductor. There are also means on the device for connecting supporting or anchor cables.

These and other new and useful objects as will appear later are secured and attained by the novel construction, combination and arrangement of parts of which my invention is composed and which will appear later, as more fully described and claimedy and shown in "the accompanying drawing in which Fig. 1 is a side elevation of my device assembled with conductor in place and showing one of the cam engaging members out of operative engagement with the conductor and clamping plate.

Fig. 2 is an end elevation of Fig. 1.

Fig. 3 is a topV assembled view of my device.

Fig. 4 is a sectional view on the line 4 4 of Fig. 3. My preferred constructionshown and described comprises three members, namely-a body member 1 provided with hook lugs 2 at each end and a longitudinal U-shaped groove to receive the conductor and having the lugs at the ends oppositely disposed with respect to the U groove; a

clamping member having a horizontal portion 4 and provided with a member 5 adapted to enter the longitudinal U-sha-ped groove 3 and engage with the trolley wire 6 or conductor and also having eyes 7 for the reception of a supporting, strain, anchor cable and the like; and a pair of'cam tips 8 each provided with lips 9 at one end to engage and be formed about the conductor. The cam tips are also provided with two cam members 10 and 11 and the cam member 10 is'connected-to the tip by means of a shaft like construction 12. The shaft member 12 is adapted to engage with the hook members 2 and rotate relatively to the hook members.

The cam 1() is so' arranged that it will engage the horizontal portion 4 of the clamping memfber and the cam 11 is so arranged as vto engage the conductor when the device is properly installed upon the conductor. The parts before assembly are all separable.

In order to install the invention the parts are first disassembled. The U shaped body member 1 is then placed in position with the conductor resting in the longitudinal groove. The plate 3 is then placed in position with the member in engagement with the trolley wire 6. Onev of the cam members 8 is then placed in position with vthe member 12 engaging the interior of the hook member 2 and as'shown in the dotted line construction in Fig. 1 and the cam member is then rotated down into final position and in this operation of rotation the cam 10 engages the clamping member 4 and the cam 11 engages the conductor forcing the clamping member 4 and conductor simultaneously into position. This operation with the cam member is repeated with the other cam or both cam members may be operated into position simultaneously. This forms a secure clamp upon the trolley wire and after such installation as described the lips of the member 9 can then be peened or formed about the conductor, thereby lockingthe device as against disassembly. If desired, supporting, strain or anchor cablesmay be secured in the eye members 7.

Having shown and described my invention I do not wish to be limited to the eX- Vact construction shown and described, as there are variations which can be made and which will be readily recognized by one skilled in the art and which will come within the scope of my invention as set forth in the following claims 1.
